Medical grade titanium alloy is extensively employed in the field of bone and dental implants. However, it is important to note that this material does not possess inherent antibacterial qualities that can effectively mitigate the risk of infection to subsequent surgical procedures. This study focuses on the fabrication of TiO₂ nanotubes on the surface of Ti6Al4V in order to augment the material's bioactive characteristics. The synthesis of TiO₂ nanotubes was accomplished using the anodisation method, where the current and anodisation duration were manipulated as variables. The results obtained from the analysis of the scanning electron microscopy (SEM) information provide compelling evidence that fluctuations in the current exert substantial influence on the nanotube production process. The deceleration of the oxidation process due to low current is disadvantageous in the context of nanotube production. The acceleration of TiO₂ nanotube production is significantly enhanced by an increase in the voltage. Nevertheless, an excessive anodisation duration may result in solution saturation, hence producing abnormal development and the subsequent collapse of the TiO₂ structures.
